Genetic Parameters, Prediction of Gains and Intraspecific Hybrid Selection of Paspalum notatum Flügge for Forage Using REML/BLUP

Genetic improvement of native forage species is a sustainable alternative for maximizing livestock production. Paspalum notatum Flügge the most important grass in grasslands southern Brazil, with substantial potential available further genetic improvement. The objective this study was to quantify range parameters and predict yield gains population P. intraspecific hybrids. Results indicated hybrids had high magnitudes heritability broad average sense genotype, plus selective accuracy variation all characteristics evaluated. This REML/BLUP can contribute useful information plant selection future breeding programs. material studied showed variability Analysis 336, 332, 437, 132 male parent ‘30N’ should be included new crosses increase dry matter production notatum. Parents need selected from different groups order maximize heterosis. In addition, these parents must diallel crosses. results obtained provide improved cultivars commercialization.
